Question

Bella can run a mile in 9.54 minutes. Linda can run a mile in 8.22 minutes. How much faster can Linda run than Bella? Justify your reasoning.

Answer 1

Answer:1.16 times

Explanation:

Given

Bella can run a mile in 9.54 minutes

Linda can run a mile in 8.22 minutes

We know,
`\text{distance=speed}*\text{ time}`

Speed of Bella, for running a mile is

`\Rightarrow v_b=(1)/((9.54)/(60))=(60)/(9.54)\\\\\Rightarrow v_b=6.29\ mph`

Speed of Linda, for running a mile is

`\Rightarrow v_l=(1)/((8.22)/(60))=(60)/(8.22)\\\\\Rightarrow v_l=7.29\ mph`

So, Linda is faster than Bella, as her speed is more compared to Linda.

Linda is
`(9.54)/(8.22)=1.16` times faster than bella
