Answer:90 minutes.
Step-by-step explanation:Given:
Time taken to run the first 5 km = 30 minutes
Time spent resting = 25 minutes
Time taken to run the next 5 km = 35 minutes
Total time (t) = Time for the first 5 km + Rest time + Time for the next 5 km
t = 30 minutes + 25 minutes + 35 minutes
t = 90 minutes
So, the value of t is 90 minutes.
