Question

if he wants to bike 154 km, how long (in hours) must he ride? express your answer in hours to two significant figures. time = h submit request answer

Explanation:

Since the speed is not given, we assume a common - average cycling speed. A typical average cycling speed is about 20 km/h.

Step1: Recall the speed - distance - time formula

The formula is $t=\frac{d}{v}$, where $t$ is time, $d$ is distance, and $v$ is speed.

Step2: Substitute the values

Given $d = 154$ km and $v=20$ km/h, then $t=\frac{154}{20}=7.7$ h.

Answer:

$7.7$ h
