Question

express 89 kilometers per hour in miles per hour.

mi/hr
(round to the nearest hundredth as needed.)

approximate english and metric equivalents
1 in. = 2.54 cm
1 ft = 30.48 cm
1 yd = 0.9 m
1 mi = 1.6 km

Explanation:

Step1: Use conversion factor

We know that 1 mi = 1.6 km. To convert 89 km/h to mi/h, we divide the speed in km/h by the number of km in a mile.
Let \(v\) be the speed in mi/h. Then \(v=\frac{89}{1.6}\).

Step2: Calculate the value

\(v=\frac{89}{1.6}=55.625\).

Step3: Round to nearest hundredth

Rounding 55.625 to the nearest hundredth gives 55.63.

Answer:

55.63
