If a car is traveling 80 mph travels a certain distance in 4 3/4 hours how long will a car traveling 60 mph take to travel the same distance

Distance = rate * time
distance = 80 * 4.75 = 380 miles

For the car travelling 60 mph
time = 380 miles / 60 mph
= 6 and (1/3) hours or
6.333333333333333333333 hours.

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. if you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.
