easy math problem changing mph to m/s?

Question

if a baseball is traveling at 105 mph what is the speed in m/s?

i just need to know how to convert, i know that 1 mile = 1.61km and 1km = 10^3m



thanks

Answer 1

first figure out how many meters is 105 miles
1 mile = 10^3+10^3*.61 meter
1 mile 1610 meter
1 hr = 3600seconds
105*1610/3600 = 46.96 m/s

Answer 2

105 Mph To Km

Answer 3

105 mph means
105miles/hr
1 mile = 1.61km=1610m
1hr =60min = 3600sec
so to get the units righ t- u need to x105 by1610m and divide the answer by 3600 sec
that is
(105x1610m)/3600sec
46.96m/s

Answer 4

Use the units of measurement just as if they were fractions.
m/sec=miles/hr X hrs/min X min/sec X km/mile X m/km
.........=105 X1/60 X1/60 X 1.61/1 X 1000/1
.........=46.96 meters/sec
This concept is much clearer if you were to re-write it with the top word directly over the bottom unit. You could then see how the units "cancel out" to give you meters per sec.
Unfortunately, with my key-board all fractions have to be written with / as the dividing line, rather than _. It makes the fraction just a bit more cumbersome to see clearly.
I hope this helps.

Answer 5

8km=5m
therefore
105 miles=105/5=21
km 21*8=166
105 miles= 166 km

Answer 6

Easy. Multiply the speed in mph by 1.61 to get km/h and then by 5/18 to get to m/s.

Answer 7

1 mile = (1.61 km)(1000 m/km) = 1610 m
1 hour = 60 min = (60 min)(60 sec/min) = 3600 sec

105 m/h = 105 (1610 meters/mile)/3600 s/h
105 mph = 46.96 meters/s

Answer 8

1mile=1.61Km=1610m,
1hour=3600seconds, so
105 mph=105x1610m/3600s
=46.96 m/s.ANS.

Answer 9

168.98kph=168,980meters/hr
just multiply... from per hour to per second, think of it as there's 1hr has 60mins and 1min has 60secs to get rid of your hours units and your minutes units multiply your units and divide by 3600 to get m/s
46.92m/s

Answer 10

46.93 m/s
