A digital stop-clock measures time in minutes and seconds. The stop-clock reads 00:50 when it is started (i. e. 00 minutes 50 seconds).

It reads 02:10 when it is stopped.

What is the shortest possible time that has elapsed between starting and stopping the

stop-clock?​

01:20 (1 minute 20 seconds)

Explanation:

subtract the starting time from the stopping time to get the time used: 02:10 - 00:50 = 01:20

i think it’s a. this is because if they measured the mass of something with a mass of 150g, then their final answer would have to be approximately 150g. though all of their answers are almost 150, rosa and tran have the closest answers (or the exact answer) to the accurate one.
