Question

Aiden attended school for 408 minutes, played basketball for 138 minutes, and worked on homework for 111 minutes. Estimate how much time he spent doing these activities by rounding to the nearest ten first and then adding the rounded numbers.

Answer 1

well 660

Explanation:

well frist we will have to subtract 408 with every other number

408-138=270

270-111=159

this is what he had left

but if it's the other way around 410+140+110=660
