S drives his car and covers 37 km and 500 m in 90 minutes. What is his average speed (in km/h)?

Correct option is A

Given:

S drives his car and covers a distance of 37 km and 500 m in 90 minutes.

We need to calculate his average speed in km/h.

Formula Used:

Average Speed =$$\frac{\text{Total Distance}}{\text{Total Time}}$$​

Solution:

The total distance is 37 km and 500 m. Since 500 m = 0.5 km, the total distance is:

37 km + 0.5 km = 37.5 km

Average Speed =$$\frac{37.5 \, \text{km}}{\frac{90}{60} \, \text{hours}} = 25 \, \text{km/h}$$​

Thus, the average speed of S is 25 km/h.
