Answer:

Judy spent 55 minutes exercising

Step-by-step explanation:

Here, we want to know the amount of time Judy spent exercising.

We proceed as follows;

Mary spent 3 hours , sandy spent 50 minutes less than Mary. The amount of time spent by Sandy is thus 2hrs 10 minutes

Judy spent 1hr 15 min less, the amount of time he spent is thus

2hrs 10 minutes - 1 hr 15 min

2 hrs 10 minutes is same as 2(60) + 10 = 120 + 10 = 130 minutes

I hr 15 minutes = 60 + 15 = 75 minutes

The amount of time spent is thus 130 - 75 = 55 minutes

Erika worked 18 hours last week and 20 hours this week. If she earns $6 per hour, how much did she earn these two weeks?
Crank
Hi!

If she worked 18 hours last week and 20 hours this week, then she worked 38 hours in total, because 18 + 20 = 38.

If she earns $6 per hour, and she worked for 38 hours, then she got 38 sets of 6, which you can find the answer to by multiplying 38 and 6.

This is essentially 6 + 6 + 6 +...

38 * 6 = $228

So she earned $228 these two weeks.

Hope this helped!
