Answer 1

The distance from school to home is 170 km, and the average speed is 42.5 km/h.

Step-by-step explanation:

To find the distance from school to home, we need to calculate the distance traveled at the initial speed of 98 km/h and the distance traveled at the reduced speed of 60 km/h after the rain.

Distance at 98 km/h = 98 km/h x 4 hours = 392 km

Distance at 60 km/h = (170 km - 392 km) = -222 km (Negative because it represents the distance covered backward)

The total distance from school to home is 392 km - 222 km = 170 km.

The average speed is calculated by dividing the total distance traveled by the total time taken. Average speed = Total distance / Total time Average speed = (170 km) / (4 hours) = 42.5 km/h
