Question

It takes Rayleigh 34 minutes complete 4 problems.

At this rate, how long will she take to complete 10
problems?

Answer 1

Answer:1 hour and 15 minutes

Explanation:

so it takes her 34 minutes for 4 problems so for 2 problems its 17 minutes

and then you do the 34 times 2 because its 4 problems so you add that and that = 68 minutes and then you add 17 for the 2 problems and thats 85 minutes or 1 hour and 15 minutes

Answer 2

1 hour & 25 minutes (85 minutes)

Explanation:

Time taken for 1 problem,

→ 34 ÷ 4

→ 8.5 minutes

Now time taken for 10 problems,

→ 8.5 × 10

→ 85 minutes

Hence, answer is 85 minutes.
