umm ill guess but idk if its correct.....
D=rt
70=r(15)
÷15 ÷15
4.6666666=r
the speed of the wave is 4.6666666

Divide 70 by 15 to get your answer in wave speed/minute.

15 minutes is 1/4 of an hour. 4 x 70=? miles in an hour

The speed is 70 miles divided by 15 minutes, or 4.7 miles per minute. If you want to express this in miles per hour, multiply by 60, the number of minutes in 1 hour, and you get 282 miles per hour.

it would be:
if it travels 70 miles in 15 minutes
how many miles in 1 minute.
that would be the equation and if you solve it.....
70 miles - 15 minutes
? miles - 1 minute
70 x 1 = 15x
70 =15x
and it would be approximately 5 miles per minute.
im 97.9999 percent sure about my answer. im sorry if its wrong.

If you want miles per hour, multiply the speed by what you would mulitply the time to get 1 hour. In this case, times 4.
The wave is travelling 280 miles per hour.
4x15 mins = 60 mins or 1 hour
4x70=280 miles in one hour.

speed = distance/time
so s = 70/15
= 4.67 miles per minute
(make sure you get the units right!)
