32 miles per hour. The speed at which the car is travelling is the distance in miles that the car travels per hour. If the car travels 16 miles in 30 minutes it should then travel twice as far in one hour, since one hour is twice as long as 30 minutes (half an hour). So, the car travels 2 * 16 miles per hour, which equals 32 miles per hour.

30 minutes is 1/2 hr. If you are travelling at 70mph, the in half an hour you will travel half of 70 which is 35 miles.

eight and a half hours 425 = 50 x 8.5

Half of four miles is two miles.

This question needs more context in order to be answered. Try re-phrasing the question. If you are referring to Lewis and Clark, they travelled more than 8,000 miles in less than two and a half years on their famous expedition.

50mph x 3.5 hours = 175 miles.

Think about it. In one hour, it would travel 30 miles, and 12 is a little less than half that, so take 12/30 and see if that is near half. 12 / 30 = .40 = 24 minutes. Yep. ■

400 mph means it travels 400 miles in ONE hour. So it travels 4000 miles in ten hours. And 8000 miles in 20 hours.6000 is half way between 4000 and 8000, so 15 hours is half way between 10 and 20.Or you can just divide 6000 by 400.

It's 25 miles per half-hour, and it's also 50 miles per hour.

At 50 mph, you travel 50 miles in 1 hour.So in 30 minutes (half of an hour), you'd go half of 50 miles.So, you'd travel 25 miles.

No. Light travels at about 875 thousand times the speed of sound.

Speed = 85/2.5 = 34 mph

35 miles
