Solution:
The conversion rate is given below as

Let the number of feet he can travel in one minute be

Recall that,

Hence,
we will have the relation to be

Cross multiply, we will have

Hence,
Jamal will travel 2700 feet in one minute
Step 2:
To calculate the number of feet Jamal can travel in second, we will use the relation below

Let the number of feet in one second be


By cross multiplying, we will have

Hence,
Jamal travels at 45 feet in one second
