Question

In a police on the interstate, the suspect's car reached a speed of 88 miles per hour for the total 15 minutes. In the time, how many miles did the chase last? If the rate is in miles per hour, then the time must be in hours.

Answer 1

As always, distance = rate times time. Here, distance is unknown, but we have the speed 88 mph and the time 0.25 hour. Thus,

distance traveled during chase = (88 mph)(0.25 hr) = 22 miles.

Answer 2

→ The answer is: " 22 mi."

Explanation:

→ $\frac{88 mi}{1 h} * \frac{1 h}{60 min} * \frac{15min}{1}

= \frac{88*15}{60}$ mi.

→ The 15 cancels to "1" and the "60" cancels to "4" ,

{since: " $\frac{15}{60} = \frac{1}{4}$ " }.

→ And we have: " $\frac{88}{4}$ " mi. ;

→ " $\frac{88}{4}$ " mi. = " {88 ÷ 4} " mi. = " 22 mi. " .

→ The answer is: " 22 mi."
