I HAVE GOTTEN THE ANSWER

Max made a journey of 700km partly by train and partly by bus.He started his journey at 8.00am. by train which travelled at 50km/hr. After alighting from the train, he took a lunch break of 30 minutes. He then continued his journey by bus which travelled at 75km/hr.The whole journey took 11.75hours. Determine the distance travelled by bus.

so this is the answer
time taken by the train=x
time taken by the bus=y
subtract 30 minutes from the total time taken..hence x+y=10.75
form an equation
x+y=10.75
50x+75y=700
y=6.5
75×6.5=487.5

Answer:

487.5 km

Step-by-step explanation:

Let :

  • time taken by the train = x
  • time taken by the bus = y

Solving

  • Subtract 30 minutes from the total time taken.
  • Hence x + y = 10.75

Forming an equation

  • x + y = 10.75
  • 50x + 75y = 700
  • y = 6.5
  • 75 × 6.5 = 487.5 km
