for depreciation the formula is:

y = years

value = 29000*(1-0.12)^y

value = 29000*0.88^y

You are to drive to an interview in another town, at a distance of 270 km on an expressway. The interview is at 11:15 a.m. You p

Yuri [45]

Answer:

the least required speed is 103.88 km/h

Step-by-step explanation:

Data provided in the question:

Total distance = 270 km

Total time to reach = Time between 8 a.m and 11:15 a.m i.e 3.25 hours

Now,

For the distance of 110 km speed was 100 km/h

therefore, the time taken to cover 110 km = $\frac{\textup{Distance}}{\textup{speed}}$

= $\frac{\textup{110 km}}{\textup{100 km/h}}$

= 1.1 hour

For another 43 km speed was 42 km/h

therefore, the time taken to cover 43 km = $\frac{\textup{Distance}}{\textup{speed}}$

= $\frac{\textup{43 km}}{\textup{42 km/h}}$

= 1.0238 hours

Now,

The distance left to be covered = 270 - 110 - 43 = 117 km

Time left = 3.25 h - 1.1 h - 1.0238 h = 1.1262 h

Thus required speed = $\frac{\textup{117 km}}{\textup{1.1262 h}}$

= 103.88 km/h

Hence, the least required speed is 103.88 km/h
