Correct Answer: Option C

Explanation:
Total time for full trip = 240 / 60 = 4 hours. Time spent on first 120 km = 120 / 40 = 3 hours. Remaining time for the last 120 km = 4 - 3 = 1 hour. Required speed = 120 km / 1 hour = 120 km/h.

Question #663
Walking at 5/7 of his usual speed, a student reaches his exam center 12 minutes late. What is his exact usual time to reach the center?
A. 26 minutes
B. 35 minutes
C. 30 minutes
D. 32 minutes
Discuss

Question #672
In a 200m race, sprinter A beats sprinter B by 20 meters and sprinter C by 38 meters. In a race of 90 meters, by how many meters can B beat C?
A. 10 meters
B. 9 meters
C. 11 meters
D. 8 meters
Discuss
Get Complete Subject PDF for Maths

Correct Answer: Option B

Explanation:
When A covers 200m, B covers 180m and C covers 162m. This means in a match distance where B covers 180 meters, C covers 162 meters. Scaling down to 90 meters: B covers 90m, C covers 162 * (90/180) = 81m. Therefore, B beats C by 90 - 81 = 9 meters.
