a car us traveling 35 mph. it will rach the store in 12 minutes. How far is the store?
recall that speed is distance travelled per unit time, or
v = d/t
since the given speed is in miles per hour, we first convert the given time (the 12 minutes) to hours:
60 minutes = 1 hour ; thus
12 minutes = 0.2 hour
substituting,
v = d/t
35 = d/0.2
d = 7 miles
hope this helps~ :)
