60 bpm = 3600 beats per hour

2/5= .4

Her heart rate decreased by .4

This means:  3600 = x * .4

x = 3600/.4

x=9000

Her heart rate was 9000 beats per hour OR

9000bph = 150 bpm

Answer:

Mike can go 124 miles

Step-by-step explanation:

Car rent = $29.20

However, a customer has to pay $0.20 for every mile.

Mike has $54 to spend on the car for a day.

If he pays the car rent which is $29.20, then he has

$54 - $29.20 = $24.80 remaining

1 mile = $0.20

x miles = $24.80

By cross multiplication

0.20x = 1 * 24.80

x = 24.80/0.20

x = 124 miles
