In one hour, the car travels 70 miles. Work out (using the information already given in the question) how many kilometres are equal to 70 miles. That is the speed in km/h.
Then, multiply the speed in km/h (which you just worked out) by 4 to get the distance travelled in 4 hours.
To check your answer, work out how many miles the car would travel in 4 hours and then convert that to kilometres.

112 kph.
448 kilometres in 4 hours
The workings are, if you're interested, multiply 70 x 1.6 to get kph. Multiply the kph figure by 4 to get the distance.
That's using the data you quote, not some other conversion factor.

You keep multiplying by "1" until you get the right units: 70.5 km/hr X .62 miles/ 1 km X 1 hr / 60 minutes Now the units are what you want. Multiply 70.5 x.62, then divide by 60.

I think it is about 135-140kph!!!!!!! So really it should be the same when your travelling long distances when you look at the k's on how long you got to go but they're rearranged to how far you're away from your destination, for instance? You see a sign and it says 142 right? Well you double that and add it up into minutes then that's how far you are away. It's that simple!

1 mile = 1.60934 km
70 miles = 70 × 1.60934 km = 112.65 km
Distance = speed × time
= 112.65 × 4 = 450.60 km
