D=TxR
D=18 minutes x 10 miles/hr
D= 180 minutes miles / hr      1 hr/60 minutes
D= 3 miles

T= D/R    T= 3 miles/ 30 miles/ hr  T= 1/10/hr  6 minutes

It took Ishaan 24 minutes to go 6 miles so his average speed is D/T=R
6miles/24minutes=miles/hr  1 miles/4 minutes x 60 minutes/hr =  15 miles/hr
Ishaan's average speed was 15 mph.

As an incoming college freshman, Tina received a 10-year $9,900 Federal Direct
Ksju [112]

The amount charged on the loan which is the loan interest rate, increases as the time after the initial amount is credited into the account increases.

  • The interest on the Federal Direct Unsubsidized Loan after 4 years 6 months is <u>$1,911.195</u>

Reasons:

The given parameter are;

Loan amount, the principal, P = $9,900

Duration of the loan = 10 years

Loan interest rate, R = 4.29%

Required:

The amount of interest that will accrue while she is still in school and over the 6-months grace period for the freshman loan.

Solution:

Based on a similar question on an online source, we have;

Interest, I = P × R × T

Where;

T = The time = The time the freshman is in school + 6 months

Therefore, normally, we have;

T = 4 years + 6 months = 4.5 years

R = 4.29% = 0.0429

Therefore;

Interest, I = 9,900 × 0.0429 × 4.5 = 1911.195

The interest that will accrue while she is still in school and over the 6-months grace period for the loan,<em> I</em> = <u>$1,911.195</u>

solmaris [256]
143.7  I believe since you take 6.80*20=136+46=2.3*20

136+46=182

182*7.65%=168.08

168.08*8.95%=153.04

153.04*6.1%=143.7
