Question

A car travel 140 miles in 3 hours (with a constant speed). How far can it travel in 7 hours (with the same speed)?

Answer 1

326.666miles

Explanation:

v=distance/time (v=d/t)

d=140 miles

t=3hrs

v=d/t, v=140/3, v= 46.666mph

v=46.666mph

t=7hrs

d=?

v=d/t, d=vt, d=46.666mph x 7hrs, d= 326.666miles
