Using the relation between velocity, distance and time, it is found that:
- The speed of the wind is of 2 mph.
- The speed of the broom is of 14 mph.
<h3>What is the relation between velocity, distance and time?</h3>
Velocity is <u>distance divided by time</u>, hence:

Flying with the wind, in which
the 48-mile trip took 3 hours, hence:



Her flight home against the wind took 4 fours, hence:



Adding the two equations:



Hence:
- The speed of the wind is of 2 mph.
- The speed of the broom is of 14 mph.

Answer: He need to score 100 in next assignment to can get an A.
Step-by-step explanation:
Given: Average marks till now = 88%
Average = (sum) divided by (Number of observations)
