Lynette drove 248 miles in four hours at that rate how many hours will it take her to drive an additional 93 miles

tatyana61 [14]

Remark

The question becomes "How long does it take her to drive 248 + 93 = 341 miles?"

Answer

Set up a simple proportion.

248/4 = 341/x Cross multiply

248 * x = 4 * 341

248 x = 1364 Divide by 248

x = 1364/248

x = 5.5 hours

But you are only asked about the 93 miles.

Answer: The number of hours for 93 miles is 5.5 - 4 = 1.5

Norma-Jean [14]

Answer:

605 rupees

Step-by-step explanation:

add the parts of the ratio 3 + 4 = 7

divide the number of notes by 7 to find one part of the ratio

$\frac{77}{7}$ = 11 ← 1 part of the ratio

3 parts = 3 × 11 = 33 ← number of 5 rupee notes

4 parts = 4 × 11 = 44 ← number of 10 rupee notes

Amount of money = (33 × 5 ) + (44 × 10) = 165 + 440 = 605 rupees
