Calculate the average speed of a complete round trip in which the outgoing 300 km is covered at 97 km/h, followed by a 1.0-h lun

gizmo_the_mogwai [7]

Answer:

Average Speed is 65 km/hr

Step-by-step explanation:

To get the average speed, first we have to calculate the time spent in the round trip .

Speed= Distance/ time

So, Time= Distance/Speed

Time Outgoing= 300km/ 97km/hr

Time Outgoing=3.0927 hr

Time lunch break =1 hr

Time return= 300km/ 58km/hr

Time Outgoing=5.1724 hr

Total= 3.0927 hr+1 hr+5.1724 hr=9.2651

To get average speed, we have to divide all the distance by the time it took al the trip.

Average Speed= Distance/ time

Average Speed= 600km/9.2651 hr= 64,76 km/hr

Average Speed=64,76 km/hr ≅ 65km/hr

Answer:

Sadie's family car is more fuel efficient.

Step-by-step explanation:

Given;

Sadie's family car rating, S = 42 miles per gallon

Nanette's family car rating, N = 6 liters per 100 km

Sadie's family car rating, in liters per 100 km

$= \frac{42 \ miles}{gallon} *\frac{1.609 \ km}{1 \ mile}*\frac{1 \ gallon}{3.79 \ liters} \\\\ = (\frac{42*1.609}{3.79} )\frac{km}{liter}\\\\ = (\frac{3.79}{42*1.609} )\frac{liter}{km}\\\\=(\frac{3.79}{42*1.609} )(\frac{100}{100}) \frac{liter}{km}\\\\= (\frac{3.79*100}{42*1.609} )(\frac{1}{100}) \frac{liter}{km}\\\\= (\frac{3.79*100}{42*1.609} ) \frac{liter}{100\ km}\\\\= 5.61 (\frac{liter}{100\ km})\\\\= \frac{5.61 \ liters}{100 \ km}$

Also, Nanette's family car rating, in liters per 100 km = 6 liters / 100km.

Thus, Sadie's family car uses lesser fuel, because of this Sadie's family car is more fuel efficient.
