960/50=192

His speed is 192m/min
His speed increases by 20

192+20=212
His skiing speed is 212m/min

To find how many meters he can ski in 10 mins multiply his speed rate by 10
212*10=2120

2120m would be your answer.

I hope this helps :$

First let's find out how much he can ski per minute without his increase in speed.
To find speed we will have to divide distance by time.
960÷5=232
So his speed is 232 meters per second.
Now to this as add 20.
232+20=252
Then to find out how far he will go in 10 minutes,we will just have to multiply 252 by 10
252×10=2520
So your answer will be that Alex will go 2520 meters in 10 minutes.

Well, 1000/5 would be smaller than 2000 not bigger. You are dividing into smaller pieces not multiplying into bigger ones.

The longer piece of wire is 42.5

The shorter piece of wire is 37.5

37.5+42.5=80

37.5 matches the requirements because it is 5 smaller than 42.5 :)
