Answer: Cruz's biking is 16 miles per hour and his running speed is 10 miles per hour.
Step-by-step explanation:
Let x represent Cruz's speed when running.
He left his house at 6:00 and ran until 7:30. This means that the time spent while running is 1hour 30 minutes = 1.5 hours.
Distance = speed × time
Distance covered while running would be
1.5 × x = 1.5x
Then he rode his bike until 9:45. This means that the time he spent riding his bike is 2hours 15 minutes = 2 hours + 15/60 = 2.25 hours
His speed when biking was 1.6 times his speed when running. It means his speed when biking would be
1.6 × x = 1.6x
Distance covered while riding would be
1.6x × 2.25 = 3.6x
He covered a total distance of 51 miles. Therefore,
1.5x + 3.6x = 51
5.1x = 51
x = 51/5.1 = 10 miles per hour.
His biking speed would be
1.6 × 10 = 16 miles per hour.
Well let’s say you put $100 in the bank. And they charge 10% interest. And 10% of $100 is 10. So it would be $10 interest.
Formula
A=bh divides by 2
SUBSTITUTE
45=b9 divided by 2
MULTIPLY/DIVIDE
You can either divide by 2 or multiply by 1/2 (gets the same answer)
9 x 1/2 = 4.5
DIVIDE
45 divides by 4.5 = 10
CHECK
A= 10 x 9 divided by 2 or multiply by 1/2 (same answer) = 45
Thus, the answer is 10.
I hope this helped you understand the process!
