Question

As you walk to physics class, you start out at a speed of 2 m/s, for a time of 120 seconds (you’re really excited to get to class). Then you see your friend and slow down to a speed of 0.5m/s for 30 seconds. You stop at your locker for 40 seconds (a speed of 0 m/s). You realize that you are about to be late so you hurry to class at a speed of 1 m/s and get to class just as the bell rings (4 minutes after your trip started). How far did you travel total?

Answer 1

Answer:

The total travelled distance is $51065 \mathrm{~m}$

Explanation:

• Speed, time and distance is one of the most common and important topics in the Mathematics or Quant section.

• Calculate total speed;

$\therefore \text { Total Speed }=2+0.5+0.0+1=3.5 \mathrm{~m} / \mathrm{sec}$

• Calculate total time taken;

$\therefore \text { Total time taken }=120+30+40+14400=14590 \mathrm{sec}$

• To find total travelled distance, use the formula

$\text { Distance }=\text { Speed } \times \text { Time }$

$\mathrm{d} &=3.5 \times 14590$

$&=51065 \mathrm{~m}$
