Answer 1

Answer:

here is your answer, grab it

Step-by-step explanation:

Given-

• distance covered before breakfast- 1/8
• distance covered between breakfast and lunch-2/5
• distance covered between lunch and tea- 3/10

To find left journey we will have to add all fractions and subtract it from the whole.

so let the full journey be 1

= 1 - (1/8 + 2/5 + 3/10)

= 1 - (33/40)

= 1/1 - 33/40

= 7/40

so the left distance is 7/40

let's find the distance covered in each interval-

distance covered before breakfast-

= 80 * 1/8

= 10 km

distance covered between breakfast and lunch-

= 80 * 3/10

= 32km

distance covered between lunch and tea-

=80 * 3/10

= 24km
