Question

Liam is riding his bike at a rate of 7 miles per hour. He wants to beat his own one-day riding record. To do so, he has to ride more than 32 miles. He's already ridden 4 miles. Which statement describes how many more hours Liam must ride his bike to beat his record? He must ride more than 4 more hours. He must ride no less than 5 more hours. He must ride no more than 5 more hours. He must ride fewer than 4 more hours.

Answer 1

He must ride more than 4 more hours.

Answer 2

Liam is riding his bike at a rate of 7 miles per hour. He already rode 4 miles. To ride more than 32 miles he has to ride more than 28 miles.

So he has to ride more than $\frac{28}{7} =4\;hours$.

The correct choice is "He must ride more than 4 more hours".
